WlRE-GAUZE FOR PAPER-MACHINES.

SPECIFICATION forming part of Letters Patent No. 520,906, dated June 5, 1894.

I Application filed January 18,1894. erial No. 497,271. (No model.)

To all whom it may concern.-

Be it known that 1, PAUL TOURASSE, of La Bridoire, (Savoy,) France, have invented certain new and useful Improvementsin Wire- Gauze for Paper-Machines, which improvements are fully described in the following specification.

This invention has for its object the production of an improved wire gauze or fabric for use in paper machines, and is an improvement upon the fabric described and claimed in my Patent No. 502,087, granted July 25, 1893. The said fabric is composed of helicoidal wires interlaced and combined with straight wires inserted through the interwoven spirals, these straight wires having for their object to stifien the web or fabric in the direction of its width, without interfering with the pliability of the fabric in the direction of its length. The introduction of these straight wires between the spirals may be effected in any convenient way during the manufacture of the fabric. For paper'making purposes the web thus obtained is rolled and compressed, as described in my patent mentioned above.

The invention is illustrated in the accompanying drawings, in which 7 Figure 1 is a perspective view, and Fig. 2 a cross-section of so much of a-web as is nec' essary for purposes of explanation. Fig. 3, is a plan view of the fabric flattened.

The helices a are threaded one into the other, and at the junction,that is between the interlaced coils of adjacent spirals, are interposed the straight wires b in the direction of the width of the web, so that the loops bear against the wires 1) and not directly against each other. The web after being formed as described is flattened as specified above.

The'combination of the straight wires with the spirals effects an important improvement,

since it prevents the formation of pockets or folds, and produces rigidity widthwise without impairing the property of pliability, lengthwise, which is absolutely necessary for the passage of the fabric upon the rollers of a paper machine.

What I claim is- As a new article of manufacture, a wire gauze or fabric suitable for paper making machines, composed of wire helices threaded together and straight wires parallel with the axis of the helices between the interlaced coils of adjacent helices, the fabric being flattened so that the wires lie practically in one plane, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

PAUL TOURASSE.
